[usame-algan]

What it solves

Resolves #5159

How this PR fixes it

• Removes TagManager class and moves required logic into the gtm.ts file
• Adds @next/third-parties package
• Adds new Analytics component to initialize GA
• Replaces dataLayer calls with sendGAEvent

ToDos

• Add env variables to CI

How to test it

1. Ensure that the same events are still sent to GA

• Test this PR deployment vs. dev/staging/prod
• Do the same action in both deployments e.g. Create new transaction
• Compare collect network call data

2. Ensure events are still sent to the correct GA property

• Test property on localhost, dev, staging, PRs
• Prod property on prod
• Safe apps property when inside a safe app

Checklist

• I've tested the branch on mobile 📱
• I've documented how it affects the analytics (if at all) 📊
• I've written a unit/e2e test for it (if applicable) 🧑‍💻

📦 Next.js Bundle Analysis for @safe-global/web

This analysis was generated by the Next.js Bundle Analysis action. 🤖

⚠️ Global Bundle Size Increased

Page	Size (compressed)
global	1.06 MB (🟡 +73.08 KB)

Details

The global bundle is the javascript bundle that loads alongside every page. It is in its own category because its impact is much higher - an increase to its size means that every page on your website loads slower, and a decrease means every page loads faster.

Any third party scripts you have added directly to your app using the <script> tag are not accounted for in this analysis

If you want further insight into what is behind the changes, give @next/bundle-analyzer a try!

Details

Only the gzipped size is provided here based on an expert tip.

First Load is the size of the global bundle plus the bundle for the individual page. If a user were to show up to your website and land on a given page, the first load size represents the amount of javascript that user would need to download. If next/link is used, subsequent page loads would only need to download that page's bundle (the number in the "Size" column), since the global bundle has already been downloaded.

Any third party scripts you have added directly to your app using the <script> tag are not accounted for in this analysis

Next to the size is how much the size has increased or decreased compared with the base branch of this PR. If this percentage has increased by 20% or more, there will be a red status indicator applied, indicating that special attention should be given to this.
